I'm not sure this is the proper place on this forum to ask this question, but here goes....
I'm certain stainless and steel can be brazed together, but I have an additional challenge. I need to replace a 10" flexible pipe on a 1999 Toyota Camry exhaust system. If I buy a bolt-on part to replace what is damaged, it includes the pipe from the manifold, the flexible pipe and a catalytic converter. That part costs ten times the price of the flexible pipe I have found. The flexible pipe is the only part that has damage. The pipe over which I will slide the new stainless flexible pipe is 2 3/8th inches OD. The closest stainless flexible pipe I can find is 2 1/2 inch ID. This leaves an eight of an inch to deal with.
Unless I can find a flexible stainless pipe (length 10") with ID ends of 2 3/8ths, I am probably going to try to use the 2 1/2 ID flexible pipe and do the best I can sealing it by brazing.
If anyone knows where I can purchase a flexible exhaust pipe 10 inches long that is 2 3/8th ID, I would appreciate you pointing me to the source.
Questions.... Is brazing the way to go with this? I've done a little brazing, but am really a novice at it. Is there something I should use as a sleeve (copper, brass, steel) to take up most of that 1/8 inch?
I do a fair job with arc welding, but I think these materials are too thin for me to stick weld. I don't have tig experience.
I'm hoping to cut the old flexible portion out, slide the new flexible length in (with a sleeve, if recommended), weld or braze enough to hold the three pieces in place, then take the whole assembly off the vehicle and finish it on a workbench to ensure it is completly sealed properly.
Can I fill that much space with brazing rod? If I use a space filler (sleeve), how can I ensure the brazing material will sweat properly? What should I use for brazing rod? What flux should I use, and how is it applied?
I'm looking for advice as to whether or not this is a workable idea and what is the best route to success and safety.
